ABSTRACT:
Disclosed is a color video signal recording apparatus wherein the chrominance signal and the luminance signal are separated from the composite color video signal, the luminance signal is transformed into a frequency modulation signal and the chrominance signal is converted to have a lower frequency so that both reformed signals are recorded on a frequency multiplex basis on a recording medium. In processing a TV signal of CCIR system, the chrominance signal is controlled to have a frequency of 3/8 N.multidot.f.sub.H (where N is an odd number) and have its phase shifted by 90.degree. in every horizontal scanning period; in processing a TV signal of NTSC system, the chrominance signal is controlled to have a frequency of 3/8 N.multidot.f.sub.H (where N is an integer) and have its phase shifted by 90.degree. or 180.degree. in every horizontal scanning period, while the control being made such that 1/4 N is an integer in case of 90.degree. phase shift of (3N-2)/4 is an integer in case of 180.degree. phase shift.
